PHP - 如何返回HTML特殊字符代码？

Question

I'm working on function like this one:

function foo() {
   return '[ = ]';
}

But this returns:

[ @ ]

And I need:

[ = ]

Any ideas?

Answer 1

You could either call htmlspecialchars on your string before you output it, or you could simply replace the & in your string with a &.

Either one will make a browser show = instead of @.
